Read the passage. excerpt from My Autobiography by Mark Twain In the matter of slavish imitation, man is the monkey's superior all the time. The average man is destitute of independence of opinion. He is not interested in contriving an opinion of his own, by study and reflection, but is only anxious to find out what his neighbor's opinion is and slavishly adopt it. A generation ago, I found out that the latest review of a book was pretty sure to be just a reflection of the earliest review of it; that whatever the first reviewer found to praise or censure in the book would be repeated in the latest reviewer's report, with nothing fresh added. Therefore more than once I took the precaution of sending my book, in manuscript, to Mr. Howells, when he was editor of the "Atlantic Monthly," so that he could prepare a review of it at leisure. I knew he would say the truth about the book—I also knew that he would find more merit than demerit in it, because I already knew that that was the condition of the book. I allowed no copy of it to go out to the press until after Mr. Howells's notice of it had appeared. That book was always safe. There wasn't a man behind a pen in all America that had the courage to find anything in the book which Mr. Howells had not found—there wasn't a man behind a pen in America that had spirit enough to say a brave and original thing about the book on his own responsibility.
